The volume of a cake (same depth) is proportional to the area of the base, which is proportional to the square of the diameter (or radius).

Factor $= \left(\dfrac{12}{8}\right)^2 = \left(\dfrac{3}{2}\right)^2 = \dfrac{9}{4} = 2\dfrac{1}{4}$

The recipe ingredients should be multiplied by $2\dfrac{1}{4}$.

The textbook provides a detailed timeline of early Urdu journalism:

• 1822: Jam-e-Jahan Numa — first Persian weekly published, sometimes in Urdu, sometimes in Persian — a weekly, not a daily
• 14 January 1850: Kohinoor — started by Munshi Harsukh Rai as a weekly with circulation of 350 (the largest of its time)
• 1858: Urdu Guide — started by Maulvi Kabeeruddin from Kolkata — this was the FIRST Urdu daily newspaper
• Same year (1858): Roznamcha-e-Punjab started from Lahore as the second daily
• 1903: Zameendar started from Lahore — best newspaper of its time, first to use news agencies, circulation of 30,000, supported independence movement

Students commonly confuse the first publication in Urdu (Jam-e-Jahan Numa, 1822) with the first Urdu daily (Urdu Guide, 1858).

Paralytic ileus is the temporary cessation of bowel motility after abdominal surgery. Return of bowel function is confirmed by:

1. Passage of flatus (gas) — earliest and most reliable sign of return of peristalsis
2. Bowel sounds (return in small bowel first, usually 24–48 hrs; large bowel 48–72 hrs)
3. Passage of stool

Assessment sequence for bowel function return:

• Auscultate for bowel sounds (all four quadrants, 2 minutes each)
• Ask patient about passage of gas (flatus)
• Advance diet only after confirmed peristalsis (clear liquids → soft → regular)

Failure of bowel function to return may indicate mechanical obstruction, which requires surgical intervention — a critical distinction for Charge/Head Nurses.
